IMPROVEMENT IN COOKING-RANGES.

Specification forming part of Letters Patent No. 44,04ll, dated August30, 1864.

To all whom t may concern.-

Be it known that I, REUBEN R. FINCH, Jr., of the city and State of NewYork, have invented, made, and applied to use a certain new and usefulImprovement in Cooking- Ranges; and I do hereby declare the following tobe a full, clear, and exact description of the said invention, referencebeing had to the annexed drawings, making part of this specilication,wherein-v Figure lis a plan of said range with the top plate removed,but shown in red lines. Fig. 2 is a longitudinal section of said rangeat the line y y, Fig. l. Fig. 3 is a cross-section of the same at theline z z, Fig. 2. Fig. 4 is an elevation of the front of the range, andFig. 5 is a section through one of the ovendoors.

Similar marks ot' reference denote the same parts.

The nature of my said invention consists in a register applied betweenthe oven and fire and perforated fire-bricks or soapstone, fitted insuch a manner that dust and ashes will not pass into the oven, but saidoven can be used for roasting by the direct rays of heat from the lire.I also arrange my ilues in such a manner that the products of combustionpass at the sides and back of the oven, thence below said oven, and riseto the smoke-pipe or chimney, so as to more completely surround the ovenwith the heated products of combustion.

In the drawings, a is the bottom plate ofthe range; b b, the side or endplates; c, the back plate, and e the front plate. f is the bottom g g,the ends; h, the top and i the back plate of the oven. k is thefire-chamber; l, the ashpit; m, the grate, and n the side plate of the1ire-chamber, Figs. l and 2, of brick or metal, between which and theplate b the air descends through the holes l 1, Fig. 2, to supply thefire. o is the usual supply or chute for coal; and p is the top plate ofthe range, having the ordinary openings for pots, kettles, Ste.

The parts thus far may be of any desired size and perform theirwell-known duties, and hence do not require further description.

q is the the smoke or escape flue that is closed by the plate 2, Figs. land 8, from the top of the oven to the plate p, and provided with aswinging damper, r, on the pin or rivet 3, Fig. l, and acted upon by therod et, so that the smoke, Ste., when the tire is being lighted, can beallowed to pass directly to the flue or chimney by opening this damperfr, which damper directs the heat around below the different parts ofthe plate p without interrupting the escape ofthe products ofcombustion. When this damper r is closed, it extends from the division 2to a division, 5, Fig. l, that passes down between the back ovenplatc,t', and the range-back c, andis extended across beneath the oven in theform of a ilueplate, 6. (Shown by dotted lines in Fig. l.)

t, u, and c are liues passing down at the side ot' the oven and theback, uniting in the bottom iiue, tf, and the products of combustionpass down these ilues t, u, and o, and through the bottom flue, o', andaway by the llue q, thus thoroughly heating the oven, and that withgreat uniformity.

I provide a plate, w, that is movable, and may be placed in any desiredposition, so as to separate the oven into two compartments, that one maybe used for meats, while the other is used for baking of any desiredkind; and- I have two oven doors, a' and In the door :1: is aslide-opening or secondary door, 7, (see Figs. 4 and 5,) by the openingof which the required supply of air is admitted into the portion of theoven next the fire to convey into said fire the fumes from the meat orother articles cooking therein by the direct action of the fire, as nextexplained. The fire-bricks or soapstones n are perforated, and placed atsome little distance from the oven-plate g, so that any ashes or dustmay fall down between the two into the ash-pit, l, and theseperforations correspond with the openings that are cast in saidoven-plate g next the nre-chamber k, Figs. 1 and 2, and over theseopenings is a register-plate or slide by which they may be closed. Itwill now be seen that when this register is opened, the iire will actdirectly upon articles in said oven, to roast them by the direct rays ofheat, and at the same time the fumes are carried into the iire by thecurrent of air admitted, and the dust and ashes will not enter saidoven.

What I claim, and desire to secure by Leta ters Patent, is

1. `The arrangement of the tlues t, u, and fu, damper fr, and flue q, bywhich the heat is reg; ulated in its action on the oven, or the productsof combustion pn-ssed directly to the chimney, as set forth.

2. rlhe construction of the damper 1^, as an are of a eirele moving onthe pin 3, and teting between the plates 2 and 5, as set forth,

3. The perforated brick or soapstone n', with aspziee between that andthe oven-plate opening to the lash-pit, for the purposes specied.

4. The register-plate d in combination with the perforated brieks nl,for the purposes and as specified.

5. The slide or seeonndry door 7 in the ovendoor, for the purposes andas specified.

In Witness whereof I have hereunto set my signature this 2d day of June,A. D. 1864.
